In the article there are presented results of morphological and histochemical researches of embryogenesis after experimental autopollination of all dichogamous types (homogamous, protandrous, protoginous) of walnut (Juglans regia L.). Manual self-pollination confirms potential self-compatibility of English Walnut genotypes irrespective of flowering type. At the same-time, it should be noted that protogynous varieties have a higher fertilization percent. All varieties showed lower growing rate of” pollen tubes and delayed fertilization, at self-pollination. Experimental heitonogamy provoke more rapid embryogenetic processes within all dichogamous types. |
